DOOR LOCK.

Application filed January 31, 1921. Serial No. 441,113.

T 0 all whom it may concern.

Be it known that I, BAIrrHoLoMnw Ju- LIEN, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a certain new and useful Improvement in DoorLocks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a partof this specification.

This invention relates to improvements in door locks, and more specifically to door locks employed in connection with horizontally slidable doors such as are found on freight, mail, baggage, express and street cars, in buildings, ships and other places.

One object of the invention is to provide a door lock which may be easily manipulated to render it both operative and inoperative and wherein the construction is simple, comparatively inexpensive, and comprised of few parts.

Another object of the invention is to provide a device which will positively hold the door in closed position and lock it and which will positively prevent accidental opening of'the door'which might otherwise occur as a result of the door being subject to jarring or vibration as for instance on a moving body such as a railway or street car.

A still further object of the invention is to provide a door locking device which, in operative position, will prevent pilfering or prying open of the door without leaving visual evidence thereof.

Another object of the invention is to provide a door locking device which will readily accommodate itself to such variations as may occur in the manufacture and assembling of the parts and to such distortion as may occur in service.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described and made the subject matter of claim.

In the drawings forming a part of this specification, Figure 1 is a side elevation of a portion of a freight car showing my improvements employed in connection with the usual side door of such a car, parts being broken away in order to better accommodate the figure on the sheet. Figure 2 is an enlarged elevational view of the door locking device proper shown in Figure 1. In Figlever B, mounted ure 2, the dotted lines indicate the inoperative or open position of one of the door locking elements. Figure 3 is a horizontal, sectional view corresponding substantially to the line 3-3 of Figure 2. Figure 4; is a-hori- Zontal, sectional view upon a larger scale and corresponding substantially to the line 1-4 of Figure 2. Figure 5 is an elevational view of the fulcrum or bracket member shown in Figures 1, 2 and 3. Figure 6 is a view similar to Figure 2 illustrating another embodiment of my invention. Figures 7 and 8 are views similar to Figures 3 and a and corresponding to the section lines 7-7 and 8-8, respectively, of Figure 6. And Figure 9 is a vertical, sectional view corresponding to the section line 9-9 of F igure 6.

Referring first to the construction illustrated in Figures 1 to 5, inclusive, the side wall of a car is indicated at 10, said car being provided with the usual side door opening as indicated at 11 in Figure Said opening 11 of the car is adapted to be closed in the usual manner by a horizontally slidable door 12. In the instance shown, said door 12 is supported at its top edge by rollerrarrying brackets 13-13, the rollers of which travel upon a suitable track 14-. The bottom edge of the door is guided and confined by suitable brackets 15-15 secured to the lower edge of the car side, the door preferably having small'castings 16-16 secured thereto at its bottom edge adapted to engage the brackets 15. its will be understood by those skilled in the art, the door 12 is in closed position as illustrated in all of the figures and the rear edge of the door is at the right as viewed in Figure 1.

In carrying out my invention, I employ, broadly, a bracket or fulcrum A. secured to the side wall of the car; a pivoted element or on the bracket A; a looking element 50 rigidly secured to the car door 1:2 at the lower rear corner thereof; and a slidable bolt or seal pin D carried by the lever B.

The fulcrum or bracket A, preferably in the form of a malleable casting, is suitably rigidly secured to the side wall of the car at a point below the lower edge of the door and a short distance rearwardly of the rear edge of the door when the latter is in closed position, as best shown in Figures 1 and 2. Said bracket A is provided with a substantially centrally disposed perforated boss 17 in which is received a pivot pin 18 preferably in the form of a rivet. To the side of the boss 1? farthest from the door and in alinement with the boss, the bracket A is formed with an integral shoulder or shelf 19 the function of which will appear hereinafter. Below the boss 17, the bracket A is formed with a vertically disposed integral shoulder 20 adapted to cooperate with a shoulder 21 formed on the adjacent end of the lever eleinent B, as shown in Figure 2.

The lever element B is pivotally attached to the bracketA by said rivet pivot pin 18. The lever B is provided, however, with an elongated opening 22 through which the pivot pin extends so as to adapt the lever B for vertical movement with respect to the pivot pin when in the position illustrated in Figure 2 so that the lever B may be lifted sufficiently to have the lug 21 thereof clear the lug 20 of the bracket A and thereby permit the lever B to be swung in a clockwise direction to the inoperative position shown in Figure 2 at B*.

At its upper or free end, the lever B is deflected slightly outwardly from the side wall of the car so as to bring it into alinement with or same plane as the rear edge of the door, as shown in Figures 3 and 4. At its said free end, the lever B is provided with a rib 23 and a downwardly flaring undercut groove 24 which are adapted to cooperate with a corresponding slot 123 and rib 12d formed on the adjacent end of the locking element C. As best shown in Figure 2, the opposing faces of the ribs and grooves 23, 123; 24, 124 are inclined from the vertical in the general direction from the front upper corner of the door toward the rear lower corner. Vith this arrangement, it is evident that the lever B may be swung in a counter-clockwise direction into engagement with the locking element C and vice versa and, when the two elements are in abutting e 6 y tendency of the door 12 to shift in an' opening direction, i. e., toward the pivot or ful crum of the lever B, will place the lever B under compression.

As will be clear from the preceding, the operative end of the locking element C is disposed on the rear edge of the door 12 near the bottom thereof, although the main part of said element C, indicated at 25, is extended horizontally over the outer side of the door and rigidly secured thereto by any suitable means such as the bolts 26. In order to obtain a more extended and secure fastening to the door, a horizontally extending strap 27 may be employed forming in effect an extension of the element C, there being a common bolt for both as indicated at 26' in Figure 3.

In the construction illustrated, I have shown the bolt D as slidably mounted on the en a ement, they are interlocked.

lever B. Any suitable means may be employed for so slidably mountingthe bolt D, that shown in the drawing comprising a p n 28 carried by the lever, the same working in an elongated horizontally extending slot 29 formed in the bolt D. The bolt D may be guided by an overhanging flan e 30 and a lower lug 31 carried by the leverdl The end of the bolt D at the left, as viewed in Fig ures 2, 3 and 4, is preferably tapered as inclicated at 32 so as to facilitate its insertion through a horizontal slot 33 formed in an outwardly extending triangular shaped lug 34 made integral with the element C. With the bolt D positioned within the slot 33, as shown in the drawing, it is evident that the lever B cannot be disengaged from the looking element C. Where my locking device is employed on a railroad car, it is desirable to provide means for the use of the usual lead seal and to this end the bolt D has a small lug 35 thereon slotted as indicated at 36 inalinement with a corresponding slot 37 formed in the lug 3st. The usual lead seal may be run through the slots 36 and 37, such a seal being indicated conventionally at 38 in Figure 4.

In some instances, 1t is desirable to utilize a padlock or the like in order to prevent tampering and to provide for this contingency, the lever B and'bolt D are provided with horizontally extending flanges 39 and a0 respectively, having openings a1 therein adapted to be alined when the parts arein operative position, it being evident that the padlock may be inserted through said alined openings 41 and thereby positively prevent disengagement of the bolt D from the element 0 without first removing the padlock.

Any tendency of the door to move in an opening direction, i. e. toward the right as viewed in Figures 1 and 2, will be resisted by the lever B being prevented from rotating in a clockwise direction because of the engagement of the shoulder 21 thereon with the shoulder20'of the fulcrum or bracket A. To open the door it is first necessary to disengage the bolt D from the element C then lift the lever B so as to clear the lug 21 from the lug 20 and then swing the lever B clear of the path of the door to the position indicatedby dotted lines B in Figure 2. To

hold the lever B in its inoperative position :tion with a member therein and a door in Figures 6 to 9 inclusive, I employ a fulcrum or bracket member A; a locking lever or element B; a locking element C; a slidable bolt D; and an additional vertically slidable bolt or latch E carried by the element G.

The bracket A is or may be the same as the bracket A and has a horizontal shoulder or ledge 119 and vertical shoulder or lug 120. The lever 'B is substantially the same as the lever B except that it is not provided with any lug corresponding to the lug 21 and furthermore, the opening therein through which the pivot pin 118 extends is not elongated, thereby dispensing with vertical shifting of the lever B in order to disengage itfroin the lug 20. The lever B has lugs 143 and 142, the same as in the previously described construction adapted to cooperate with the ledge 119 and lug 120, respectively. The engaging faces of the lever B and element C are preferably the same as in the case of the construction shown in Figures 1 to 5. The bolt D is also mounted on the lever B in substantially the same way and it and the lever B are provided with similar means for accommodating a padlock. Detailed description of these features is not deemed necessary.

The locking element C is formed with an outwardly extended integral lug 134 having a horizontally extending opening 133 therein to accommodate the bolt D. 'The latter is preferably enlarged near its lefthand end as viewed in Figure 8, as indicated at 50 so as to provide sufficient metal to permit of the bolt being vertically slotted or notched asindicated at 51, said notch being located to the left of the lug 134: when the parts are in operative position. Said notch 51 is disposed in alinement with the lower end 52 of the latch E which is vertically slidablv mounted on an upwardly extended part 53 of the locking element C as by means of the rivet 54: and elongated. slot The lower end of the latch E may be guided in a perforated flange 56 formed on the element C. At its lower end, the latch E is slotted as indicated at 57. said slot being disposed below the bolt D when the parts are in locked position so as to receive a sealing strip 58 and thereby prevent unlocking of the parts without leaving visual evidence thereof.

I have herein shown and described what I now consider the preferred manner of earrying out the invention but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
